SYDNEY, Jan. 25 (Xinhua) -- Huawei Technologies, on Monday asked a U.S. District Court to prevent Motorola from illegally transferring Huawei's intellectual property (IP) to Nokia Siemens Networks ("NSN"), officials of Huawei told Xinhua in Sydney, Australia on Tuesday.As a leading player in providing next generation telecommunications network solutions, Huawei took this action as NSN seeks to complete its 1.2 billion U.S. dollars acquisition of Motorola's wireless network business.Since 2000, Huawei and Motorola have had a cooperative relationship in the radio access network and core network businesses, where Motorola has resold Huawei wireless network products to customers under the Motorola name. During this period, Motorola was provided with products and confidential Huawei IP developed by Huawei's team of more than 10,000 engineers.Since the July 2010 announcement by NSN of its purchase of Motorola's wireless network business, Huawei has tried to ensure that Motorola does not transfer this confidential information to NSN.According to officials of Huawei, Motorola's failure to adopt measures sufficient to ensure that Huawei's proprietary information remains confidential has compelled the company to file for the appropriate legal protection of its rights.The officials said Huawei respects the rights of intellectual property holders and is equally committed to the protection of its own innovations and intellectual property.Nearly half of Huawei's 100,000 plus employees are engaged in research and development and Huawei allocates an average of 10 percent of all revenues to R&D annually. By the end of 2010, Huawei had applied for 49,040 essential patents on a global basis.

WASHINGTON, March 9 (Xinhua) -- U.S. space shuttle Discovery landed safely at the Kennedy Space Center in Florida on Wednesday, ending its nearly 27-year flying career as the world's most- traveled spaceship.According to NASA, Discovery touched down at 11:57 a.m. EST ( 1657 GMT) after a 13-day resupply mission to the International Space Station (ISS)."For the final time: wheels stop," Discovery's commander Steven Lindsey called out as the shuttle rolled to a full stop.Discovery lifted off on Feb. 24 from the Kennedy Center and arrived at the space station on Feb. 26.During the mission, the astronauts installed a spare closet module on the space station, completed some important repairs and delivered the first humanoid robot, though it will need more time to be assembled and made operational.The 330-pound R2 consists of a head and a torso with two arms and two hands. Once it is unpacked -- likely several months after its arrival at the station -- it will initially be operated inside the Destiny laboratory for operational testing, but over time both its territory and its applications could expand.Aboard the station, its primary job for now is teaching engineers how dexterous robots behave in space. However, the hope is that through upgrades and advancements, it could one day venture outside the station to help spacewalkers make repairs or additions to the station or perform scientific work.

SAN FRANCISCO, April 8 (Xinhua) -- YouTube on Friday launched YouTube Live, a homepage for live content on the site and a new live-streaming platform.As part of the service, the world's largest video-sharing website introduced a new browse page, www.youtube.com/live, where users can view live events and add upcoming events to their calendars.YouTube said it would gradually roll out a live streaming beta platform, which will allow certain YouTube partners with accounts to stream live content on the website.The new service will "integrate live streaming capabilities and discovery tools directly into the YouTube platform for the first time," YouTube said in a blog post.U.S. media recently reported that YouTube is planning a major overhaul and is negotiating with Hollywood and music producers for materials to offer on a lineup of new channels, with the aim to compete with broadcast and cable television.

BAODING, Hebei, Feb. 3 (Xinhua) -- Chinese President Hu Jintao Thursday called for efforts to promote welfare for senior citizens and vowed to improve the country's health care system to make medical services more affordable.Hu made the call during a three-day inspection tour in Baoding City of northern province of Hebei starting on Tuesday, during which he visited orphans, talked to senior citizens and extended festival greetings to local residents.At a nursing center in Shunping County of Baoding City, Hu offered New Year greetings to senior citizens, orphans and staff of the center.Hu wished the senior citizens good health and a long life, encouraged orphans to study hard, and thanked the staff for the care given to the aged.The Communist Party of China (CPC) and the government will make strenuous efforts to improve the welfare of seniors and make sure their difficulties are solved and they have access to better services, Hu said.When visiting Zhao Helou, a Baoding retiree who has been hospitalized several times and living in difficult circumstances, Hu promised assistance from the Party and the government to help Zhao tide over her problems.The health care and medical insurance system would be improved in the future to tackle people's difficulties in medical care, Hu promised.During his visit to Baoding, Hu also inspected drought conditions at wheat fields, joined villagers during New Year celebrations and extended Spring Festival greetings to passengers, station workers and volunteers.Hu, who is also general secretary of the CPC Central Committee, was briefed on the work of Hebei's provincial committee of the CPC and the provincial government during his tour.

LOS ANGELES, April 3 (Xinhua) -- People with lower levels of vitamin D are more likely to have stiffer arteries and an inability of blood vessels to relax, U.S. researchers have found.This finding also applies to people who are in general good health, according to researchers from the Emory University School of Medicine.The researchers presented their findings on Sunday at the annual American College of Cardiology meeting in New Orleans.Impaired vascular health in correlation with lower vitamin D levels contributes to high blood pressure and the risk of cardiovascular disease, the researchers say.The study involved 554 participants, with the average age of 47 and generally healthy.The average level of 25-hydroxyvitamin D (a stable form of the vitamin reflecting diet as well as production in the skin) in participants' blood was 31.8 nanograms per milliliter. In this group, 14 percent had 25-hydroxyvitamin D levels considered deficient, or less than 20 nanograms per milliliter, and 33 percent had levels considered insufficient, less than 30 nanograms per milliliter.The researchers monitored the ability of participants' blood vessels to relax by inflating and then removing a blood pressure cuff on their arms. To allow blood to flow back into the arm, blood vessels must relax and enlarge -- a change that can be measured by ultrasound. The researchers also made other measurements of smaller blood vessels and examined the resistance to blood flow imposed by the arteries.
